YARN-OILING DEVICE.

Application led December 27, 1924. l Serial No. 758,383.

This invention relates to improvements in devices for applying oil to yarns particularly adapted for use in connection with machines for winding yarns upon tubes or caps to be afterward knitted or woven into fabrics.

l-leretofore difficulty has been experienced in applying oil to yarn uniformly so that some parts of the yarn wound upon the tube or cap would contain greater or less percentages of oil than other parts thereof, resulting in variations in the length of the knitted web 0r woven cloth produced from the oiled yarn, and also in other objections.

The object of my present invention is to overcome these objections, and l accomplish my object by the provision of a novel, simple and eiiicient yarn oiling device which will apply the oil uniformly to the yarn at all times. L

With the foregoing and related objects in Y view, my invention consists in the novel construction, combination and arrangement of parts hereinafter described and claimed.

In the accompanying drawings, illustrating my invention,

Figure 1 is a sectional elevation of a yarn oiling device embodying my invention.

Figure 2 is a view, partly in section and partly in elevation, of the oil feeding pipe and adjuncts.

Referring to the drawings, 2 designates a supporting bar or rail which may form part of the framework of a yarn winding machine when my invention is employed in connection therewith.

Secured to the bar 2 and extending therefrom is a bracket 3 which may be of any construction, shape and size suitable for its intended purpose. This bracket 3 supports a receptacle for oil 4, which, as herein shown, is in the form of a trough, having round rods or bars 5 connected thereto and extending longitudinally thereof, the trough and rods being shown in transverse section in Fig. 1 of the drawings. Y

Journaled in suitable bearings on the ends of the trough 4 is a sha-ft 6 which extends longitudinally of the trough and carries an oil delivery roller 7. Part of the periphery of the roller extends into the trough 4 and it is adapted to besubmerged in oil 8 therein, and the remainder of the periphery of the roller 7 is exposed above the level of the oil 8.

The shaft 6 and therewith the rolle-r 7 are adapted to be rotated at a constant speed by any suitable mechanical means, and, when they are thus rotated, the exposed portion of the periphery of the roller 7 carries a lm of oil supplied to it from the body of oil 8 within the trough 4. As the roller 7 is thus rotated, the yarn 9 to be oiled is drawn over the roller 7 and the forward rod 5 at a uniform rate of speed and in a manner to cause the yarn to bear with slight pressure upon the peripheryof the roller 7 andthereby be supplied with oil from the oil film vby the exposed part of the roller.

Rising fixedly from .the bar 2 is a bracket lOrcarrying forwardly projecting arms 11 and 12 having loops 13 and 14 formed therein. Supported within the loopsl and 14 is an oil reservoir 15, preferably in theform of a glass jar having an opening in the bottom thereof which is closed by a metal head or cap 16 screwed onto a neck 17 formed on the jar 15.

The central portion of the cap 16 is per forated for the reception of the upper end of a pipe 18 which is secured thereto b y nuts 19 screwed onto the pipe 18 and clamping the head 16 between packing washers 2O interposed between the nuts 19 and the head 16. The pipe 18 is thus fixedly secured to the head 16 in a-'manner to communicate with theinterior of the jar or reservoir rfhe pipe 18 extends from the head 16 down into the trough or receptacle 4 laterally of the roller 7'. The lower end of thepipe 18 opens into the trough 4 through al longitudinal slot- 21 formed in a s icle wall of the pipe. The exterior ofthe lower end portion of thepipe 18 is screw-threaded and carries a regulating collar 22 and a locking collar 23 screwed onto the same. The regulating collar 22 closes the yupper portion of the slot 21 and it is adapted to be screwed up or down on the pipe 18 'to vary the height of its lower end which controls the highest point of communication between theV pipe 18 and the trough 4 through the slot 21. The locking collar 23' is provided to be screwed tight against the regulating collar 22 to lock it indifferent positions of adjustment.

It will now be understood that oil from the reservoir 15 will be Supplied to the trough 4 through the pipe 18 and be maintained at a constant level within the trough 4 substantially at the highest point of com# inunicatioii between the pipe 18 and trough 4- throiigli the-,slot 21', because,4 asgiapidly as munication,V air will be admitted to the reservoir 15 through the. slot 21 and-pipe 18,7peiifA Vinittinpgroil to flow iioin the reservoir'to the trough 4, and; when the oil Within tliieitrough Y closes such point of communication, oil Will caiv eeaieto ievv from theiee'eivoir. lltgivilllaieof be understood that the oil level maintained ivi-thin the' tro'ugli'li`v niay be -i'faised oi"` leWer-'ed the pipe 1-8.
